如何检查日期间隔是否在另一个间隔中

import datetime

def check_interval_within(another_interval_start, another_interval_end, interval_start, interval_end):
    if interval_start >= another_interval_start and interval_end <= another_interval_end:
        return True
    else:
        return False

# 示例数据
another_interval_start = datetime.datetime(2022, 1, 1)
another_interval_end = datetime.datetime(2022, 12, 31)
interval_start = datetime.datetime(2022, 3, 1)
interval_end = datetime.datetime(2022, 5, 31)

if check_interval_within(another_interval_start, another_interval_end, interval_start, interval_end):
    print("日期间隔在另一个间隔中")
else:
    print("日期间隔不在另一个间隔中")
